【発明の属する技術分野】
本発明は、タイヤの成型において、タイヤ構成用のリボン状部材を、供給部から送り出すとともに、成型用ドラムの回転により引き出すようにして給送する際の、前記リボン状部材の送り出し速度制御方法及び装置に関するものである。
【０００２】
【従来の技術と発明が解決しようとする課題】
タイヤの成型において、タイヤのトレッドゴムの下のベルト層上に補強層として比較的細幅の、例えば８ｍｍ幅や１５ｍｍ幅のタイヤ構成用のリボン状部材を、スパイラル状に巻回して貼り付けることが行われている。
【０００３】
このようなタイヤ構成用のリボン状部材を巻回し貼り付け成型する工程は、図２のように、ロール状に巻回されて供給部に設置されているリボン状部材（Ａ）を、モータ（１０３）により回転駆動される送り出しローラ（１０２）により送り出すとともに、ループ状に垂下させて一時リザーブする縣架調整部（１０５）を介して成型用ドラム（Ｄ）の回転により引き出すようにして給送し、成型用ドラム（Ｄ）上で巻回成型するようにしている。
【０００４】
この際、前記リボン状部材（Ａ）の送り出し側と引き出し側との間に縣架調整部（１０５）が介在してはいても、両方の速度を合わせておく必要がある。
【０００５】
従来は、オペレータが、前記リボン状部材（Ａ）の引き出し速度と送り出し速度の差を、例えば縣架調整部（１０５）でのリザーブ量の増減を目視により確認しながら送り出し用モータの出力を調整し、送り出し速度を引き出し速度に同調させるように調整を行っている。
【０００６】
ところが、前記リボン状部材（Ａ）の引き出し速度は、成型用ドラム（Ｄ）上でのリボン状部材（Ａ）の巻回径によって変化し、また製品ロットによっても異なる。通常、１日に数回〜十数回、多いときには２０回を越えるロットの段替えがあり、その都度、オペレータによる送り出し速度の調整が必要になり、この調整にかなりの時間を要し、オペレータの作業負担が大きくなっている。
【０００７】
また、同一ロットにおいても、ドラム上での巻回径の変化によって引き出し速度が変動するため、その変動に応じてオペレータによる送り出し速度の微調整を必要とする上、この微調整が難しく、調整が不完全であると、送り出し速度と引き出し速度の同調にずれが生じ、その結果、縣架調整部（１０５）でのリザーブ量が大きく変動することになる。通常、このリザーブ量の変動を光電センサよりなるリザーブ量下限検出センサ（１１７）で検出して、リザーブ量が一定量より多くなると、送り出し用モータ（１０３）を一定時間低速にしてコントロールするようにしているが、その回数が多くなると、作業上のトラブルや調整不良による不具合が発生し易いと言う問題があった。
【０００８】
そのため、従来装置では、リボン状部材の送り出し速度、ひいてはリボン状部材の巻回成型作業の高速化の障害となっており、また段替えの際の速度調整、ひいては段替え作業に時間がかかり、作業効率が劣ることになる。
【０００９】
また、前記の縣架調整部でループ状に垂下させるリザーブ量を大きくするのは、大きなスペースをとることになり、好ましいものではない。
【００１０】
本発明は、上記に鑑みてなしたもので、タイヤの成型において、タイヤ構成用のリボン状部材を成型用ドラムに給送するための送り出し速度を、成型用ドラムの回転による引き出し速度に同調させるようにした制御方法と装置を提供するものであり、段替え等の際のオペレータによる速度調整を不要にし、段替え作業時間の短縮、高速での送り出しを可能にし、巻回成型の作業効率を向上させることができるように発明したものである。
【００１１】
【課題を解決するための手段】
本発明は上記の課題を解決するものであり、請求項１の発明は、タイヤ構成用のリボン状部材を、送り出し用モータの駆動により供給部から送り出すとともに、ループ状に垂下させて一時リザーブする縣架調整部を介して成型用ドラムの回転により引き出して給送する際、前記縣架調整部からのリボン状部材の引き出し速度を検出し、該検出値に基づく速度指令により前記の送り出し用モータを制御し、リボン状部材の送り出し速度を前記引き出し速度に同調させることを特徴とする。
【００１２】
請求項２の発明は、前記の送り出し速度の制御方法を実施する制御装置にかかるものであり、タイヤ構成用のリボン状部材を、供給部から送り出すとともに、成型用ドラムの回転により引き出すようにして給送する装置において、供給部からリボン状部材を送り出すための送り出し用モータと、送り出されたリボン状部材をループ状に垂下させて一時リザーブする縣架調整部と、該縣架調整部からのリボン状部材の引き出し速度を検出する速度検出手段と、該速度検出手段により検出された引き出し速度の検出値に基づく速度指令を前記送り出し用モータの制御アンプに出力する手段とを備え、前記送り出し用モータによるリボン状部材の送り出し速度を前記引き出し速度に同調させるように構成してなることを特徴とする。
【００１３】
請求項３の発明は、前記の送り出し速度制御装置において、速度指令を制御アンプに出力する手段は、前記引き出し速度の検出値に対して任意の値を加算できる速度補正ボリュームを有し、前記検出値に電気的ロス等の補正を行なって速度指令を出力するように設けられてなるものである。
【００１４】
請求項４の発明は、前記の送り出し速度制御装置の縣架調整部において、リボン状部材の一定量以上の垂下リザーブ量を検出して、送り出し用モータの制御アンプに低速指令を出力するリザーブ量下限検出センサを設けたものである。
【００１５】
請求項５の発明は、前記の送り出し速度制御装置において、リボン状部材の引き出し速度を検出する速度検出手段が、引き出し側の給送用ローラに取り付けたロータリーエンコーダであり、パルス信号により引き出し速度を検出するとともに、このパルス信号を電圧量に変換して出力するパルス／電圧変換器を備えてなるものである。
【００１６】
【作用】
上記した本発明のリボン状部材の送り出し速度制御方法及び装置によれば、縣架調整部より引き出し側の引き出し速度を検出して、この引き出し速度の検出値に同調させるように、送り出し用モータによるリボン状部材の送り出し速度を制御するので、オペレータによる段替え毎の送り出し速度の調整が不要となり、段替えに要する時間を大幅に短縮できる。しかも、送り出し速度が引き出し速度と同調するため、縣架調整部のリザーブ量の変動も少なく、特に高速化にも問題なく対応でき、調整不良による不具合やトラブルの発生も少なくなる。また縣架調整部に大きなスペースをとる必要もなくなる。
【００１７】
また、成型用ドラムの回転による引き出し速度が、巻回径の変動や加速時に大きく変動しても、これに伴って送り出し速度も変動して同調するため、オペレータによる運転中の微調整は不要であり、常に引き出し速度に対応した速度で送り出すことができる。
【００１８】
【発明の実施の形態】
次に本発明の実施の形態を図面に示す実施例に基づいて説明する。
【００１９】
図１は本発明を実施する送り出し速度制御装置の概略構成説明図である。同図において、（Ａ）はタイヤ構成用のリボン状部材を示し、ロール状に巻回した状態で供給部に巻き出し可能にセットされる。
【００２０】
（２）は前記リボン状部材（Ａ）の送り出しローラであって、送り出し用モータ（３）とチエン、ベルト、歯車等の伝動手段（４）により連結されており、該モータ（３）により回転駆動されることにより、前記供給部のリボン状部材（Ａ）を送り出すように設けられている。図の場合、前記送り出しローラ（２）より供給部側に第２の送り出しローラ（２０）が配され、前記送り出しローラ（２）とチエン等の伝動手段により回転伝達可能に連結されており、リボン状部材（Ａ）を両送り出しローラ（２０）（２）の下側および上側に掛けることにより、送り出し作用を確実に行えるようになっている。
【００２１】
（５）は前記送り出しローラ（２）から送り出されるリボン状部材（Ａ）をループ状に垂下させて送り出し側と引き出し側の速度差を吸収するように一時リザーブするためのフェスツーンと称する縣架調整部である。（Ａ１）は垂下したリボン状部材（Ａ）のループ部を示している。
【００２２】
（６）（７）は前記縣架調整部（５）からのリボン状部材（Ａ）の引き出し側に配した回転自由な給送用ローラ、（８）はサービサ等の貼り付け用供給手段を示している。（Ｄ）はタイヤ成型用のドラムであり、モータ等の駆動手段（図示省略）により回転駆動され、前記ローラ（６）（７）および前記貼り付け供給手段（８）を経て供給される前記リボン状部材（Ａ）を、該ドラム（Ｄ）の回転により引き出しながら、該ドラム（Ｄ）上でスパイラル状に巻回成型できるように設けられている。すなわち、前記リボン状部材（Ａ）は、その先端部を貼り付けた状態での該ドラム（Ｄ）の巻回成型のための回転により、所定の速度で引き出されることになる。
【００２３】
そして、前記リボン状部材（Ａ）の送り出し速度の制御装置は、次のように構成されている。
【００２４】
前記縣架調整部（５）からのリボン状部材（Ａ）の引き出し側の一つの給送用ローラ（７）に、この引き出し速度の速度検出手段として、該ローラ（７）の回転により引き出し速度の検出を行うロータリエンコーダ（１１）を設ける。このロータリエンコーダ（１１）としては、例えばローラ（７）の回転に同期してパルス信号を発するパルスジェネレータを利用し、パルス信号により引き出し速度を検出するとともに、このパルス信号を電圧量に変換して出力するパルス／電圧変換器（１３）を備えている。
【００２５】
前記の電圧量に変換された引き出し速度の検出値に基づく速度指令を送り出し用モータ（３）の制御アンプ（１６）に出力する手段は、該装置の立ち上げ時等において、モータの電気的ロス等の速度補正を行うための速度補正ボリューム（１５）を備えてなり、前記の引き出し速度の検出値に対して前記補正のための任意の値（定数）を加算して速度指令を前記送り出し用モータ（３）の制御アンプ（１６）に出力するように設けられている。
【００２６】
従って、装置立ち上げ時に、例えば縣架調整部でのリザーブ量などを目視しながら、前記速度補正ボリューム（１５）により送り出し速度を引き出し速度に一致させるように補正すれば、以後の段替え時等における速度補正は不要であり、引き出し速度の検出値に対して速度補正がなされて速度指令が制御アンプ（１６）に出力されることになる。
【００２７】
前記送り出し用モータ（３）は、前記制御アンプ（１６）により前記の速度指令に基づいてインバータ制御され、引き出し速度に同調した送り出し速度で回転するように設けられている。
【００２８】
また、前記縣架調整部（５）には、リボン状部材（Ａ）のループ状の垂下部分における所要の高さ位置に、垂下するループ部（Ａ１）によるリザーブ量が一定量以上になったときにこれを検出する光電センサ等よりなるリザーブ量下限検出センサ（１７）が設けられており、該センサ（１７）が一定量以上のリザーブ量を検出したときに、送り出し用モータ（３）の制御アンプ（１６）に低速指令の信号を送るように設けられている。制御アンプ（１６）は、前記の信号を受けると、前記送り出し用モータ（３）を、一定時間あるいは前記センサ（１７）がループ部（Ａ１）を検出しなくなる状態まで低速に制御するように構成される。
【００２９】
上記の制御装置を利用した送り出し速度の制御方法について説明する。
【００３０】
タイヤ構成用のリボン状部材（Ａ）を成型用ドラム（Ｄ）上に引き出して巻回成型する際、送り出し用モータ（３）により送り出しローラ（２）を回転駆動させて、供給部のリボン状部材（Ａ）を縣架調整部（５）に送り出すとともに、リボン状部材（Ａ）の先端部を貼り付けた状態での成型用ドラム（Ｄ）の回転により、前記縣架調整部（５）からローラ（６）（７）および貼り付け供給手段（８）を経て引き出しながらスパイラル状に巻回し成型する。
【００３１】
この際、前記ドラム（Ｄ）の回転によるリボン状部材（Ａ）の引き出し速度を給送用ローラ（７）に設けたロータリーエンコーダ（１１）によりパルス信号で検出するとともに、このパルス信号をパルス／電圧変換器（１３）により電圧量に変換し、この引き出し速度の検出値に基づく速度指令を前記送り出し用モータ（３）の制御アンプ（１６）に出力する。この速度指令値は、装置立ち上げ時に速度補正ボリューム（１５）により電気的ロス分等を加算するように調整し補正した値である。こうして送り出しモータ（３）が制御アンプ（１６）により前記の速度指令に基づいてインバータ制御され、引き出し速度に同調した送り出し速度で回転するように制御される。これにより、リボン状部材（Ａ）は、引き出し速度に同調した送り出し速度で送り出されることになる。
【００３２】
そのため、製品ロットの段替え毎の送り出し速度の調整が不要となり、段替えに要する時間を大幅に短縮できる。また運転中の微調整も不要になり、オペレータによる調整作業を大幅に軽減できる。しかも、送り出し速度が引き出し速度に同調するため、縣架調整部の垂下リザーブ量の変動も少なく、特に高速化にも問題なく対応でき、調整不良による不具合やトラブルの発生も少なくなる。また、成型用ドラムの回転による引き出し速度が、巻回径の変動や加速時に大きく変動しても、これに伴って送り出し速度も変動して同調できるため、オペレータによる調整は全く不要になる。
【００３３】
なお、縣架調整部（５）における垂下リザーブ量が一定量を越えると、これを光電センサ（９）により検出して、送り出し用モータ（３）に低速指令を出力して、送り出し速度を低速にし、リザーブ量を減少させる。このリザーブ量が一定量より少なくなれば、上記の通常の制御を行う。
【００３４】
【発明の効果】
上記したように本発明の送り出し速度の制御方法及び装置によれば、タイヤ成型工程において、タイヤ構成用のリボン状部材の送り出し速度を、成型用のドラムの回転による引き出し速度に同調させることができるため、段替え等の際のオペレータによる送り出し速度の調整を不要にして、オペレータの作業を軽減して、段替え時間を大幅に短縮できる。
【００３５】
しかも運転中のあるいは加速時の引き出し速度の変動にも対応できるため、運転中のオペレータによる速度調整も不要になる。
【００３６】
また、送り出し側と引き出し側の間の縣架調整部のリザーブ量の変動も小さくなるため、調整不良による不具合やトラブルの発生が少なく、その上リボン状部材の送り出し速度の高速化が可能になり、タイヤ成型における巻回成型効率を向上できる。

BACKGROUND OF THE INVENTION
The present invention provides a method for controlling the ribbon-shaped member feed speed when a tire-shaped ribbon-shaped member is fed out from a supply unit and fed out by rotation of a molding drum in tire molding, and It relates to the device.
[0002]
[Prior art and problems to be solved by the invention]
When molding a tire, a relatively narrow, for example, 8 mm or 15 mm width ribbon-like member for tire construction is wound on and adhered to a belt layer under the tread rubber of the tire as a spiral. Has been done.
[0003]
As shown in FIG. 2, the step of winding and pasting the ribbon-shaped member for tire construction is performed by rotating the ribbon-shaped member (A), which is wound in a roll shape and installed in the supply unit, with a motor ( 103) and the feed roller (102) that is driven to rotate, and is drawn out by the rotation of the molding drum (D) through the rack adjustment unit (105) that is suspended in a loop and temporarily reserved. However, it is wound-molded on the molding drum (D).
[0004]
At this time, it is necessary to adjust both speeds even if the frame adjusting portion (105) is interposed between the feeding side and the drawing side of the ribbon-like member (A).
[0005]
Conventionally, the operator adjusts the output of the feeding motor while visually checking the difference between the drawing speed and the feeding speed of the ribbon-like member (A), for example, the increase / decrease of the reserve amount in the rack adjusting section (105). The feed rate is adjusted to synchronize with the draw rate.
[0006]
However, the drawing speed of the ribbon-shaped member (A) varies depending on the winding diameter of the ribbon-shaped member (A) on the molding drum (D), and also varies depending on the product lot. Usually, there are lot changeovers of several to a dozen times a day, more than 20 lots a day, and each time it is necessary to adjust the delivery speed by the operator, and this adjustment takes a considerable amount of time. The work burden is increasing.
[0007]
Also, even in the same lot, the drawing speed fluctuates due to the change in the winding diameter on the drum, so it is necessary to make fine adjustment of the feed speed by the operator according to the fluctuation, and this fine adjustment is difficult and adjustment is difficult. If it is incomplete, there will be a deviation in the synchronization between the delivery speed and the withdrawal speed, and as a result, the reserve amount in the rack adjustment section (105) will vary greatly. Normally, the change in the reserve amount is detected by a reserve amount lower limit detection sensor (117) comprising a photoelectric sensor, and when the reserve amount exceeds a certain amount, the delivery motor (103) is controlled at a low speed for a certain time. However, when the number of times increases, there is a problem that troubles due to work and poor adjustment are likely to occur.
[0008]
Therefore, in the conventional apparatus, it has become an obstacle to speeding up the ribbon-shaped member feeding speed, and hence the ribbon-shaped member winding molding work, and it takes time to adjust the speed at the time of the changeover, and thus the changeover work, Work efficiency will be inferior.
[0009]
In addition, it is not preferable to increase the reserve amount to be hung down in a loop shape by the above-described rack adjusting portion because it takes a large space.
[0010]
The present invention has been made in view of the above, and in the molding of a tire, the feeding speed for feeding the ribbon-shaped member for forming the tire to the molding drum is synchronized with the drawing speed by the rotation of the molding drum. The control method and apparatus are provided, speed adjustment by the operator at the time of changeover is unnecessary, shortening the changeover work time, enabling high-speed feeding, and improving the work efficiency of winding molding. Invented so that it can be improved.
[0011]
[Means for Solving the Problems]
The present invention solves the above-mentioned problems, and the invention according to claim 1 sends out a ribbon-like member for constituting a tire from a supply portion by driving a delivery motor and suspends the ribbon-like member in a loop shape. When pulling out and feeding by rotation of the molding drum through the rack adjustment section, the pull-out speed of the ribbon-like member from the rack adjustment section is detected, and the above-mentioned feeding motor is detected by a speed command based on the detected value And the feeding speed of the ribbon-like member is synchronized with the pulling speed.
[0012]
The invention according to
[0013]
According to a third aspect of the present invention, in the delivery speed control device, the means for outputting a speed command to the control amplifier has a speed correction volume capable of adding an arbitrary value to the detection value of the drawing speed, and the detection It is provided to correct the electric loss or the like to the value and output a speed command.
[0014]
According to a fourth aspect of the present invention, there is provided a reserve amount for detecting a certain amount or more of droop reserve amount of the ribbon-like member and outputting a low speed command to the control amplifier of the feed motor in the rack adjusting portion of the feed speed control device. A lower limit detection sensor is provided.
[0015]
According to a fifth aspect of the present invention, in the delivery speed control device, the speed detection means for detecting the withdrawal speed of the ribbon-like member is a rotary encoder attached to the feed roller on the withdrawal side, and the withdrawal speed is determined by a pulse signal. A pulse / voltage converter that detects and converts the pulse signal into a voltage amount and outputs the voltage amount is provided.
[0016]
[Action]
According to the method and apparatus for controlling the feeding speed of the ribbon-shaped member of the present invention described above, the feeding motor detects the pulling speed on the pulling side from the rack adjusting unit and synchronizes with the detected value of the pulling speed. Since the feeding speed of the ribbon-like member is controlled, it is not necessary to adjust the feeding speed for each stage change by the operator, and the time required for the stage change can be greatly shortened. In addition, since the feed-out speed is synchronized with the pull-out speed, there is little fluctuation in the reserve amount of the rack adjustment unit, particularly high speed can be dealt with without any problem, and problems and troubles due to poor adjustment are reduced. Moreover, it is not necessary to take a large space in the rack adjustment section.
[0017]
In addition, even if the drawing speed due to the rotation of the molding drum fluctuates greatly when the winding diameter changes or accelerates, the feed speed also fluctuates and synchronizes accordingly, so there is no need for fine adjustments during operation by the operator. Yes, it can always be sent out at a speed corresponding to the drawing speed.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described based on examples shown in the drawings.
[0019]

[0021]
(5) is a frame adjustment called a festoon for temporarily reserving the ribbon-like member (A) fed from the feed roller (2) in a loop so as to absorb the speed difference between the feed side and the draw side. Part. (A1) shows the loop portion of the suspended ribbon-like member (A).
[0022]

[0024]
As a speed detecting means for this pulling speed, one pulling speed is provided to one feeding roller (7) on the pulling side of the ribbon-like member (A) from the rack adjusting section (5) by rotating the roller (7). A rotary encoder (11) for detecting the above is provided. As this rotary encoder (11), for example, a pulse generator that emits a pulse signal in synchronization with the rotation of the roller (7) is used to detect a drawing speed by the pulse signal and convert the pulse signal into a voltage amount. An output pulse / voltage converter (13) is provided.
[0025]

And a speed correction volume (15) for performing a speed correction such as the above, and adding an arbitrary value (constant) for the correction to the detected value of the drawing speed to send a speed command for the sending It is provided to output to the control amplifier (16) of the motor (3).
[0026]
Therefore, when the apparatus is started up, for example, by visually checking the reserve amount at the rack adjustment unit and the like, the speed correction volume (15) is used to correct the delivery speed so that it matches the drawing speed. No speed correction is required, and speed correction is performed on the detected value of the drawing speed, and a speed command is output to the control amplifier (16).
[0027]
The delivery motor (3) is inverter-controlled based on the speed command by the control amplifier (16), and is provided to rotate at a delivery speed synchronized with the withdrawal speed.
[0028]
Further, in the rack adjusting part (5), the reserve amount by the loop part (A1) drooping at a required height position in the loop-like drooping part of the ribbon-like member (A) is a certain amount or more. A reserve amount lower limit detection sensor (17) comprising a photoelectric sensor or the like for detecting this sometimes is provided, and when the sensor (17) detects a reserve amount of a certain amount or more, the reserve motor (3) A low speed command signal is sent to the control amplifier (16). Upon receiving the signal, the control amplifier (16) is configured to control the sending motor (3) at a low speed for a certain period of time or until the sensor (17) does not detect the loop part (A1). Is done.
[0029]
A delivery speed control method using the above-described control device will be described.
[0030]
When the tire-shaped ribbon-shaped member (A) is drawn out on the molding drum (D) and is wound-molded, the feeding roller (2) is rotationally driven by the feeding motor (3), and the ribbon-shaped member of the supply section The member (A) is sent to the rack adjustment section (5), and the rack adjustment section (5) is rotated by the rotation of the molding drum (D) with the tip of the ribbon-shaped member (A) attached. Then, it is wound and formed into a spiral shape while being pulled out from the rollers through the rollers (6) and (7) and the attaching and supplying means (8).
[0031]
At this time, the drawing speed of the ribbon-like member (A) due to the rotation of the drum (D) is detected by a pulse signal by a rotary encoder (11) provided on the feeding roller (7), and this pulse signal is converted into a pulse / pulse. A voltage converter (13) converts the voltage into an amount of voltage, and outputs a speed command based on the detected value of the drawing speed to the control amplifier (16) of the delivery motor (3). This speed command value is a value that is adjusted and corrected so that an electrical loss or the like is added by the speed correction volume (15) when the apparatus is started up. In this way, the delivery motor (3) is controlled by the control amplifier (16) based on the speed command, and controlled to rotate at a delivery speed synchronized with the withdrawal speed. As a result, the ribbon-like member (A) is fed out at a feeding speed synchronized with the drawing speed.
[0032]
For this reason, it is not necessary to adjust the delivery speed for each product lot changeover, and the time required for the changeover can be greatly reduced. In addition, fine adjustment during operation is unnecessary, and the adjustment work by the operator can be greatly reduced. In addition, since the feed-out speed is synchronized with the pull-out speed, there is little variation in the amount of droop reserve of the rack adjustment unit, and particularly high speed can be dealt with without any problem, and the occurrence of problems and troubles due to poor adjustment is reduced. Further, even if the drawing speed due to the rotation of the molding drum fluctuates greatly at the time of fluctuation of the winding diameter or acceleration, the feeding speed can be fluctuated and synchronized with this, so adjustment by the operator is completely unnecessary.
[0033]
When the amount of droop reserve in the rack adjustment unit (5) exceeds a certain amount, this is detected by the photoelectric sensor (9), and a low speed command is output to the motor (3) for sending, and the sending speed is reduced. And reduce the reserve amount. If this reserve amount is less than a certain amount, the above-described normal control is performed.
[0034]
【The invention's effect】
As described above, according to the delivery speed control method and apparatus of the present invention, in the tire molding process, the delivery speed of the ribbon-shaped member for tire construction can be synchronized with the withdrawal speed by the rotation of the molding drum. Therefore, it is not necessary to adjust the sending speed by the operator at the time of changing the setting, so that the operation of the operator can be reduced and the changing time can be greatly shortened.
[0035]
In addition, since it is possible to cope with fluctuations in the drawing speed during operation or acceleration, speed adjustment by an operator during operation is also unnecessary.
[0036]
In addition, since the fluctuation in the reserve amount of the rack adjustment unit between the delivery side and the withdrawal side is reduced, there are few problems and troubles due to poor adjustment, and the ribbon-like member delivery speed can be increased. The winding molding efficiency in tire molding can be improved.
